IEEE 802.11x Key Features
•
•
Single-band 2.4 GHz IEEE 802.11b/g/n.
•
•
FM receiver unit supports HCI for communication.
®
Support for 2.4 GHz Broadcom TurboQAM data
rates (256-QAM) and 20 MHz channel
bandwidth.
Low-power consumption improves battery life of
handheld devices.
•
FM receiver: 65 MHz to 108 MHz FM bands;
supports the European Radio Data Systems
(RDS) and the North American Radio Broadcast
Data System (RBDS) standards.
•
•
•
•
•
•
Integrated iTR switch supports a single 2.4 GHz
antenna shared between WLAN and Bluetooth.
Supports explicit IEEE 802.11n transmit
beamforming.
•
•
Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound.
Tx and Rx Low-density Parity Check (LDPC)
support for improved range and power efficiency.
Automatic frequency detection for standard
crystal and TCXO values.
Supports standard SDIO v2.0 and gSPI host
interfaces.
General Features
Supports Space-Time Block Coding (STBC) in
the receiver.
•
Supports a battery voltage range from 3.0V to
4.8V with an internal switching regulator.
Integrated ARM Cortex-M3 processor and on-
chip memory for complete WLAN subsystem
functionality, minimizing the need to wake up the
applications processor for standard WLAN
functions. This allows for further minimization of
power consumption, while maintaining the ability
to field-upgrade with future features. On-chip
memory includes 512 KB SRAM and 640 KB
ROM.
•
•
Programmable dynamic power management.
4 Kbit One-Time Programmable (OTP) memory
for storing board parameters.
•
•
Can be routed on low-cost 1 x 1 PCB stack-ups.
74-ball WLBGA package (4.87 mm × 2.87 mm,
0.4 mm pitch).
•
•
153-bump WLCSP package (115 μm bump
diameter, 180 μm bump pitch).
™
Security:
•
OneDriver software architecture for easy
– WPA and WPA2 (Personal) support for
powerful encryption and authentication.
migration from existing embedded WLAN and
Bluetooth devices as well as to future devices.
– AES in WLAN hardware for faster data
encryption and IEEE 802.11i compatibility.
Bluetooth and FM Key Features
•
Complies with Bluetooth Core Specification
Version 4.1 with provisions for supporting future
specifications.
– Reference WLAN subsystem provides Cisco
Compatible Extensions (CCX, CCX 2.0, CCX
3.0, CCX 4.0, CCX 5.0).
•
•
Bluetooth Class 1 or Class 2 transmitter
operation.
– Reference WLAN subsystem provides Wi–Fi
Protected Setup (WPS).
Supports extended Synchronous Connections
(eSCO), for enhanced voice quality by allowing
for retransmission of dropped packets.
•
•
Worldwide regulatory support: Global products
supported with worldwide homologated design.
Multimode wireless charging support that
complies with the Alliance for Wireless Power
(A4WP), the Wireless Power Consortium (WPC),
and the Power Matters Alliance (PMA).
•
•
Adaptive Frequency Hopping (AFH) for reducing
radio frequency interference.
Interface support — Host Controller Interface
(HCI) using a high-speed UART interface and
PCM for audio data.
